Definition

Aerodynamic-- relative to racing, aerodynamics is the engineering and science of how air affects the car's handling, speed, and overall performance. As air passes over a moving car it creates drag and downforce. Both are a function of the friction and turbulance of the air as it passes over, under, and around the vehicle. The goal in aerodynamic engineering is to introduce enough downforce to increase the car's cornering speeds without adding so much drag as to penalize it's top speed. The right balance between the two will produce the fastest possible lap times. Too much downforce might improve cornering speeds, but limit high-speed acceleration and top speed so that even with fast corner speeds, there is an overall time loss.
